Fix S3253 FP: Conflicts with CS8983 - A 'struct' with field initializers must include an explicitly declared constructor.

[rjgotten]

Description

S3253 is raised on empty constructors that must be added to readonly structs containing field initializers, as per CS8983.

Repro steps

public readonly struct Example
{
  public Example() { }
  
  public bool Foo { get; init; } = true;
}

Expected behavior

S3253 is not raised, because the constructor is actually required.

Actual behavior

S3253 is raised.

Known workarounds

None. Suppress the rule.

Hi @rjgotten! I confirm this to be an FP indeed, your issue has been added to our backlog and we will try to tackle it in a future sprint.
Thanks for reporting this!
